Welcome to the ocean of the 22 nd century! I am your tour guide. At this time, the ocean has been very different from the ocean in 2 1 century: a vast ocean, from blue to green, beautiful and spectacular. Look! Power stations and desalination plants stand on the sea, and the ocean becomes an underwater space. Transparent and hard glass pipes are the road to "Haicheng". You can walk freely on the seabed as long as you are coated with the potion invented by people. Look at the bustling underwater city: there are small indoor gardens, cinemas, and water and electricity are all supplied by ourselves. Can meet the needs of cultural and recreational life of offshore oil production workers. The floating city is supported by eight tall pillars. Put them away and you can sail like a boat. In the future, many offshore factories will be built in the sea near raw material production sites or markets to provide materials for urban residents at sea. Here, people can walk and play with fish. . . . . . This is the ocean of the 22 nd century!
